SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 439,742, dated November4, 1890.

Application filed August 9, 1890.

To all whom it may concern:

Be it known that I, HENRY P. CAYCE, a citizen of the United States,residing at San Marcos, in the county of Hays and State of Texas, haveinvented certain new and useful Improvements in Sash-Balances; and I 'dode clare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention has relation to sash balances and hoisters; and it consistsin the novel construction and arrangement of its parts.

In the accompanying drawings, Figure 1 is a face view of a window-frameand sash with my invention attached thereto. Fig. 2 is a longitudinalsectional view of 1, showing the left-hand side. Fig. 3 is also alongitudinal sectional View of Fig. 1, showing the righthand side. Fig.4 is a detail view.

My invention is described as follows: I make my sash A with a groove a,in their upper edge. Near both ends of said grooves are journaledpulleys a. The construction of the upper and lower sash is identical. In

" the top of the frame and on each side of the window are journaledpulleys a and a respectively. One end of a rope C is securely fixed tothe top of the frame at point 0; then it runs under the pulleys a inthe'groove a, of the upper sash, then up and over the pulley a then itdescends to the lower sash and runs under the pulleys a in the groove aof said lower sash; then it ascends and passes "over the pulley a fromwhich it runs down to a cleat B. Said cleat consists of a right and leftwing, with a V-shaped groove b between the two. One end of each of thesewings tapers in a straight line upward and outward to a point, and saidpoints indicate opposite directions. Said cleat is also provided withperforations I), through which pass screws which attach said cleat tothe window-frame.

My invention is operated as follows: When the sash are in the positionas shown in Fig.

Serial No. 361,508. (No model.)

1, and it is desired to raise the lower one, this can be done by simplypulling cord 0, and when the sash is raised to the desired height thecord is brought down under the lower point of the cleat B, then up inthe groove b, and under the upper point of said cleat. This will holdthe sash in position. When the sash are in the position as shown in Fig.1, and it is desired to lower the upper one, this can be done byunwinding cord 0 from the cleat and letting it run over the pulley erThe weight of the upper sash will cause it to descend, and when it isdown asufficient distance the cord can be wound around the cleat. Thusthe saidupper sash Will be held in the desired position. When the sashare in the position last above described and it is desired to raise theupperone, place one hand on the lower sash and pull the cord with theother. Then the sash is closed, the cord is Wound around the cleat. Whenthe sash are in the position as shown in Fig. 1, and it is desired toraise the lower one and lower the upper one at the same time, all thatis necessary to be done is to push the lower sash up, and the upper sashwill of its own weight desoend, and thus we have the weight of one sashbalancing the weight of another.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The combination of a window-frame provided with the pulleys a and a sashA, provided with the grooves a, and pulleys a, working in said grooves,and cord 0, having one end attached to the upper part of the frame at a,passing thence under pulleys a in the upper sash, thence" over pulley athence down and under pulleys co in the lower sash, thence up and overpulley a thence down to a cleat B, all substantially as shown anddescribed, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
